Title: Improvements in the manufacture of dielectrics for electrolytic capacitors
IPC: C25D11/26
Filed: 1960-05-13
Abstract: An electrode of an electrolytic capacitor is manufactured by vacuum evaporating a layer of a semi-conducting sub-oxide of Al, Ta, Ti, Zr or Nb on to a metal or insulating support and subjecting the layer so formed to electrolytic oxidation to form at least a surface layer of the oxide.  A layer of titanium sub-oxide is produced by evaporating TiO2 powder at a temperature of between 1500 DEG  C. and 2000 DEG C., which temperature is sufficient to cause partial decomposition of the oxide, with or without the presence of a moderate reducing agent. The electrolytic oxidation may be performed in a solution of a borate, citrate or tartrate in water, glycerin or glycol.

Title: Method for the formation of hard metal deposits
IPC: C23C16/30
Filed: 1974-04-18
Abstract: 1465819 Chemical vapour deposition of hard metal coatings CHEMETAL CORP 18 April 1974 [7 May 1973] 17092/74 Heading C7F In the chemical vapour deposition of hard metal on a substrate, a gaseous volatile halide of a Group IVA, VA or VIA metal is reacted with oxygen or an oxygen containing substance when the metal is W or Mo or with an oxygen free reducing agent when the metal is other than W or Mo, to deposit a liquid phase metal compound which is reacted with a B, Si or C containing gas which also includes hydrogen when the metal is W or Mo. With W or Mo halides the liquid phase may be an oxide or oxyhalide formed by reacting the halide up to 1000‹C with oxygen, water, CO, alcohols, ketones, ethers, ethylene oxide, or CO saturated with water vapour. With the other metals i.e. Ti, Zr, Hf, V, Nb, Ta and Cr a lower halide liquid phase is formed by reducing the halide either by passing it through metal chips or by reduction with hydrogen above 700‹C. The liquid deposit is then reacted with a B, C or Si containing gas which is preferably present in the initial halide gas mixture so that the deposit is formed in a one stage process. The substrates may be graphite, refracting oxides, cemented WC, W, Mo, Ti or Fe, Ni or Co base alloys. A diffusion coating of B, Si, C or N2 may be formed on the Fe, Co or Ni base alloys by pre-treating with e.g. boron chloride and hydrogen above 600 C, before depositing the hard metal. The substrate may also be stripped from the deposit to form a free standing hard metal.

Abstract: 647,862. Photo-electric cells. EDISON SWAN ELECTRIC CO., Ltd. June 28, 1948, No. 17321. [Class 39 (i)] In a process for the manufacture of photoelectric cells having a cathode of alkali metal deposited on a metal base layer, which may be antimony, tin, lead or bismuth, one of the metals magnesium or barium is vaporized in the chamber with the cathode to remove residual gases. It is stated that the deposition of these metals on the cathode improves the characteristics of the cell. As described, a thin layer of antimony is evaporated on to a nickel sheet in vacuo, fabricated in the form of a cathode. The cathode is then mounted on a stem and which also carries the anode and a support carrying a caesium getter pellet and a nickel disc to which is welded a small strip of aluminium. A mica disc prevents deposition on the window. The electrode structure is then sealed with a glass envelope which is exhausted, baked and cooled. The caesium pellet and magnesium are then fired by eddy current heating. Finally the cell is baked at 100‹ to 200‹ C., while exhausting is continued, and then sealed off. The Provisional Specification mentions the use of aluminium as an alternative to magnesium or barium.

Title: Improvements in radiation-detecting devices
IPC: G02B23/12
Filed: 1948-07-01
Abstract: 664,362. Infra-red detectors. OFFICE NATIONAL D'ETUDES ET DE RECHERCHES AERONAUTIQUES. July 1, 1948 [July 4, 1947], No. 17740/48. Class 40 (iii). [Also in Group XX] A device for detecting infra-red radiation comprises reflecting or refracting elements for concentrating the radiation into a portion of space occupied by a medium of given refractive index so as to modify this index, and a phase contrast optical apparatus is disposed so that said portion of space.is located across the path of a light beam passing through said apparatus whereby the latter indicates the presence of infra-red rays. As shown in Fig. 1, light from a source 1 is collimated by a lens 2 and is focused by a lens 3 on to an opaque screen 4, adjacent which is a lens 5. A parallel beam of infrared rays is refracted into the focal plane P-P of lens 2 so that the refractive index in a zone 7a thereof is modified and diffraction of the rays from source 1 passing through this zone occurs. These diffracted rays pass through lenses 3 and 5 so that an image 0 of source 1 is focused on a screen P<SP>1</SP>-P<SP>1</SP>, this image indicating that infra-red radiation is concentrated on zone 7a. The screen P<SP>1</SP>-P<SP>1</SP> may be of the usual kind or may be replaced by a photographic plate, a photo-electric cell or a bolometer. The air layer in plane P-P may be replaced by a transparent plate or by a fluid held between two transparent plates. In another form, the beam of infra-red rays is concentrated by a concave mirror on to an air pocket and causes diffraction of part of the beam from a light source placed near the centre of curvature of the mirror. The air pocket may be formed by a sleeve attached to a transparent plate. Alternatively, air pockets may be arranged in the form of a honeycomb structure and the radiation concentrated thereon. In the form shown in Fig. 3, light from source 1 is collimated by lens 2 and passes into an internally reflecting prism 81 separated by a small air space from a second internally reflecting prism 8 whereby the light is directed through a lens 3 and is focused on an opaque screen 4. A mask 9 is disposed between prisms 8 and 81 and a beam of infrared rays is directed through an aperture 9‹ in the mask to cause diffraction of part of the light beam, which part is focused by lenses 3 and 5 on a photo-electric cell 10. In another arrangement, the diffracted light is focused by lens 5 on an iconoscope, the output of which is amplified and transmitted to a cathode-ray tube. The Specification as open to inspection under Sect. 91 refers also to the detection of ultraviolet rays, sound and X-rays and to the detection of stresses and electronic bombardments. This subject-matter does not appear in the Specification as accepted.
